Application filed November 16, 1908. Serial No. 462,956.

To all whom it may concern:

Be it known that I, J osnPl-I ZIEG, a citizen of the United States, andresident of St. Louis, Missouri, have invented certain new and usefulImprovements in Motors, of which the following is a specification,containing a full, clear, and exact description, reference being had tothe accompanying drawings, forming a part hereof.

My invention relates to motors, the object of my invention being toconstruct a motor especially adapted for vehicles wherein springs undertension are used for furnishing the motive power, and which motor isequipped with simple means whereby the springs are readily compressed tostore power therein, and which means is readily controlled by theoperator.

To the above purposes, my invention consists in certain novel featuresof construction and arrangement of parts which will be hereinafter morefully set forth, pointed out in the claims, and illustrated in theaccompanying drawings, in which:

Figure 1 is a plan view of the frame of a vehicle having my improvedconstruction of motor thereon; Fig. 2 is a vertical section taken on theline 2-2 of Fig. 1; Fig. 3 is an enlarged detail section taken on theline 33 of Fig. 1; and Fig. 4 is a detail section taken on the line t-tof Fig. 1.

Referring by numerals to the accompanying drawings: 1 designates theframe of a vehicle, which is mounted in the usual manner upon front andrear axles 2 and 3, provided with the usual supporting wheels 4 those onthe rear axles being the driven wheels. Hinged to the side rails of theframe 1 at points adjacent the ends thereof are bars 5, the free ends ofwhich terminate adjacent the longitudinal center of the frame, andinterposed between the ends of the frame 1 and these bars 5 are leafsprings 6. Hinged to the outer ends of the bars 5 and projecting inwardtoward the longitudinal center of the frame 1 are secondary bars 7,against which bear the free ends of leaf springs 8, the opposite ends ofwhich are fixed to the bars 5.

8 designates cross bars, the ends of which are rigidly fixed to the siderails of the frame 1 a short distance away from the front and rear endrails of said frame, and fixed to these cross bars 8 and to the endrails of the frame 1 are metal plates 9, which form bottoms for thecompartments in which all of the springs of the vehicle are located.

Hinged to each one of these plates 9 a short distance away from thecross bars 8 and in the longitudinal center of the frame 1 are bars 10,the outer ends of which terminate adjacent the side rails of the frame1, and bearing against the outer ends of these bars 10 are the free endsof heavy leaf springs 11. Secondary bars 12 are hinged to the inner endsof the bars 10, and bearing a ainst said secondary bars are the freeends of leaf springs 13, the opposite ends of which are fixed to thebars 10. Journaled in bearings 1 1 fixed to the front end rail of theframe 1 is a drum 15, one end of which carries a friction brake wheel16, around which passes a friction band 17, which is connected to andoperated in the usual manner by a lever 18 on the side of the frame 1convenient to the operators seat. Carried by the opposite end of thedrum is a gear wheel 19, with which meshes a pinion 20. Journaled insuitable bearings and formed integral with this pinion 20 is a beveledpinion 21, which meshes with a large beveled gear wheel 22, the shaft ofwhich is mounted in suitable bearings 23, and located 011 the shaftcarrying this beveled gear wheel 22 is a crank handle 24. Locatedadjacent the center of the frame 1 and arranged for rotation in suitablebearings is a transversely disposed shaft 25, on which is looselymounted a drum 26, and carried by said drum is a pawl 27, the point ofwhich is adapted to engage the teeth of a ratchet wheel 28, which isrigidly fixed on the shaft 25. Carried by the drum 26 is a sprocketwheel 29, and operating thereon is a sprocket chain 30, which passesaround a small.

sprocket wheel 31 fixed on a shaft 32, which latter is arranged forrotation in suitable bearings carried by the frame 1, and said shaftbeing located a short distance in front of the shaft 25. Fixed on theshaft 32 is a large sprocket wheel 33, around which passes a sprocketchain 34, which latter drives a small sprocket wheel 35 fixed on thetransversely disposed shaft 36 arranged for rotation in suitablebearings on the frame 1, and

said shaft 36 being located a short distance to the rear of the shaft25.

Arranged for rotation in suitable bearings on the frame 1 and located ashort distance to the rear of the shaft 36 is a shaft 37, and fixedthereon is a small sprocket wheel 38, driven by a sprocket chain 39which passes around a large sprocket wheel 40 fixed on the shaft 36.Loosely mounted on the shaft 37 is a sprocket wheel 11, the hub of whichis provided with a clutch face adapted to be engaged by the face of aclutch l2, which is arranged to rotate with and slide upon the shaft 37,and which clutch is connected in the usual manner to the end of anoperating lever 13, and which lever is connected to and actuated by alever 1 1 arranged on the frame 1, convenient to the operators seat.Passing around the sprocket wheel 11 is a sprocket chain 15, whichpasses around a sprocket wheel 46 fixed upon the rear axle 3. Looselymounted upon the shaft 37 and on the opposite side of the clutch 42 fromthe sprocket wheel 41 is a pulley 47, and operating thereon is a twistedcable or belt 18, which passes around a corresponding pulley t9 fixed onthe rear axle 3, and the hub of the pulley 4:7 is provided with a clutchface adapted to be engaged by one of the faces of the clutch 42, andwhich last mentioned construction provides means whereby reverse motionis imparted to the rear axle 3. Fixed to the drum 15 is one end of acable 50, which extends to and passes once or twice around the drum 26,said cable extending from said drum to and around a pulley 51 arrangedon the rear end rail of the frame 1, and said cable extends from thencearound two sets of pulleys 52 and 53, there being three pulleys in eachset, and the pulleys 52 being journaled in a block 5 1 fixed to the rearend rail of the frame 1 adjacent the pulley 51, and the set of pulleys53 being carried by a block 55 which travels backward and forward nearthe center of the frame 1. The end of the cable 50 opposite the endconnected to the drum 15 is attached to the rear end rail of the frame 1adjacent the block 54. Fixed to the block 55 bearing the pulleys 53 isone end of a cable 56, which extends to the front end of the frame 1 andaround a pair of pulleys 57 arranged on the front end rail of saidframe, and said cable extending from thence rearward to and around theupper one of a pair of pulleys 58 arranged in a block 59, said cablepassing from thence around a single pulley 60 carried by a block 61 infront of the block 59, and said cable passing from the pulley 60 to andaround the lower one of the pair of pulleys 58, and the end of saidcable extending from thence to the block 61, to which it is fixed.

Secured to the block 61 are the ends of a pair of cables 62, whichextend forward around a pair of pulleys 63, journaled on the cross bar8" adjacent the front end rail of the frame 1, and from this pair ofpulleys 63 the cables 62 extend outward in opposite directions aroundpulleys (3 1 journal'ed at the ends of the cross bar 8" just mentioned,and the forward ends of said cables 62 are attached to the outer ends ofthe pair of secondary bars 12 at the forward end of the frame 1. Thesecond pair of cables 65 are attached to the block 61 and extend fromthence forward around a pair of pulleys 66 journaled at the center ofthe front end rail of the frame 1, and from thence said cables 65 extendrearward and are attached to the pair of secondary bars 7 at the forwardend of the frame 1. A pair of cables 67 are attached to the block 59 andextend from thence around suitably located pulleys 68, and the oppositeends of said cables are attached to the outer ends of the pair ofsecondary bars 12 at the rear end of the frame 1. A second pair ofcables 69 are attached to the block 59 and extend from thence rearwardaround a pair of pulleys 70 carried by the rear end rail of the frame 1,and the ends of said cables are secured to the inner ends of the pair ofsecondary bars 7 at the rear end of the frame 1.

To compress and store power in all of the springs, which power isutilized in driving the vehicle, the crank handle 2t is engaged, and byrotating the shaft carrying the beveled wheel 22 rotary motion isimparted to the drum 15 through the medium of the pinion 20 and gearwheel 19, and as said drum 15 is rotated the cable 50 will be woundthereon, which action draws the block 55 carrying the pulleys 53.rearward, or toward the block 5 1, and as a result the cable 56 will bepulled in such a manner as to draw the blocks 59 and 61 together, whichaction necessarily draws all of the cables 62, 65, 67 and 69, andas theends of all of these last mentioned cables are connected to the ends ofthe secondary bars 7 and 12, said bars will be swung upon their hing-esin such a manner as to compress all of the springs 6, 8, 11 and 13,thereby storing power therein. During this operation of compressing thesprings, the drum 26 will rotate freely upon the shaft 25 withoutimparting movement thereto, owing to the ratchet and pawl connectionbetween said drum and shaft. After all of the springs have beencompressed to the proper degree, the various parts are held againstreverse movement by the engagement of the brake band 17 upon the brakewheel 16, which prevents the drum 15 from rotating, and when said brakeband is released by means of the lever 18, the combined power stored inthe various springs is exerted upon the various secondary bars andcables to cause the cable 50 to unwind from the drum 15, and as thisaction takes place the drum 26 will necessarily be rotated, and: as thepawl 27 carried by said drum engages the teeth of the ratchet wheel 28,said ratchet wheel and the shaft 25 carrying the same will be rotated.The rotary motion thus obtained is transmitted by means of the sprocketchains 30, 34 and 39 to the shaft 37, and when the clutch a2 is throwninto engage ment with the hub of the sprocket wheel 41, the rotarymotion will be transmitted from the shaft 37 to the rear axle 3 of theve hicle by means of the sprocket chain 45, and as a result the vehiclewill be driven forward. The various sprocket wheels located on theshafts 25, 32, 36 and 37 and rear axle 3 are made in proper andproportionate sizes in order to obtain the proper speed for the rearaxle.

When all of the springs are compressed to store power therein, the block55 is drawn rearward into a position adjacent the series of pulleys 52,and the pulleys 58 and 60 occupy positions immediately adjacent eachother at the center of the frame, and as the vehicle is moved forward asa result of the power exerted by the springs, the pulleys 58 and 60 willgradually move away from one another and the pulley 55 will graduallymove forward through the frame of the vehicle.

The operator of the vehicle, by means of the lever 18 which actuates thebrake band 17, controls the speed of the vehicle, and when it is desiredto cause the vehicle to run backward, the operator, by means of thelever la, shifts the clutch as into engagement with the clutch face onthe hub of the sprocket wheel 47, and as the cable as operating on thepulleys 4:7 and 49 is crossed, a reverse motion will be imparted to therear axle 3, resulting in the backward travel of the vehicle.

A motor of my improved construction can be very cheaply manufactured andoperated, and the springs furnishing the motive power for the motor canbe readily compressed, owing to the great leverage ob tained by the useof the blocks and cables and the. gearing used in imparting rotarymotion to the drum 15.
